A method for controlling a wind turbine includes receiving operational data of at least one component of the wind turbine. The operational data includes a time-series of one or more high speed signals both before, during, and after an anomaly. Further, the high speed signal(s) may be digital or analog signals. The method also includes storing the operational data. Moreover, the method includes analyzing the stored operational data to identify a specific type and location of the anomaly using at least one of pattern recognition, machine learning, or rules-based conditions. In addition, the method includes determining an appropriate response action for the specific type and location of the anomaly. Further, the method includes adjusting a control parameter of the wind turbine. Thus, the method includes implementing the appropriate response action for the specific type and location of the anomaly.

The invention provides a method for stabilising a wind turbine blade (106), the method comprising, attaching (S2) an air blowing arrangement (201) to the blade, detecting (S4) an oscillation of the blade, and operating (S5) the attached air blowing arrangement to provide a thrust to counteract the oscillation.

The present invention discloses a helicopter hoisting platform for a wind turbine nacelle cover, the helicopter hoisting platform comprising a composite layer and a plurality of metal plates arranged on the outer surface of the composite layer, wherein the plurality of metal plates forms a conductive network electrically connected to a ground connection.

An assembly (127) for a wind turbine (100) includes a housing (126) having a first bearing (150) and a second bearing (154). A shaft (142) extends axially within the housing (126) and is supported by the first bearing (150) and the second bearing (154) for rotation relative to the housing (126). A radially outer portion of the shaft (142) includes at least one shaft engagement formation (146) positioned between the first bearing (150) and the second bearing (154). A retention mechanism (156) is moveable axially between: an engaged position in which it can engage the shaft engagement formation (146), such that rotation of the shaft (142) is constrained; and a disengaged position in which the retention mechanism (156) cannot engage the shaft engagement formation (146), thereby allowing rotation of the shaft (142). Additionally, a method of operating such an assembly.

Provided is an alignment tool for a cutting arrangement including a cutting apparatus with a cutting edge for treatment of a workpiece, especially a rotor blade of a wind turbine, in which the alignment tool includes at least one fixation means for fixing the alignment tool to the workpiece and at least one guiding structure to guide the cutting edge of the cutting tool.
